CVE-2026-13076: MongoDB

Medium severity, CVSS 6.5. EPSS: 0.4% chance of exploitation in the next 30 days.

An authenticated user can cause a {{mongod}} process to be terminated by the operating system under memory pressure by performing a specific data type conversion operation within MongoDB's aggregation framework. The behavior stems from disproportionate memory consumption during this operation, and requires both write access to the database and the ability to run aggregation queries.

Affected products

• MongoDB MongoDB: from 8.3.0, before 8.3.7 (fixed in 8.3.7)
